I saw this artwork in the Ghosts of Dragonspear Castle test module for D&D fifth's beta test, and it struck me, so I snapped a photo on my phone so I could look it up later. I finally got around to using Google image search to find it, which led me here.

My phone cam photo has been sitting on my desktop for months with the file name "Cool Elf.jpg" and it is very rad. Well done.
